T o (L76 107mm it may concern.'

Be it known that l. FREDERICK G. JORDAN. a citizen of the llnited States. residing at,

Cement. in the county of Penti Oreille and State of qWashington. have invented certain new and useful Improvements in Dampprooing Concrete Bodies, oi' which. the following is a specification.

This-invention relates to means and devices for perfect-ing damp and water-infoofing cement and concrete articles. work and structures. and pertains especially to relative and registering arrangement of dampproofing elements within such tconcrete articles. work and structures.

I The principal object of the invention is' to provide plural elements, impenetrableby water, damp or moisture. which shall he` vcontained in and constitute a component part of a concreteWalI, bloclnvslab or. structure. said elements having concrete-holding apertures alternating with each other and with like apertures in like opposite and alternating damp-proofing elements and thereby afford damp-proof concrete bodies for universal use. said concrete holders form a concrete bond between said plu ral impenetrable elements. and said elements also constituting concrete, reinforcement. similar to answering the same purpose as the reinforcen'ient devices covered by my Patent No. 1.294.278.

The saine reference characters denote the saine parts' throughout the several views of thc drawings. Y

Several views of the drawings are used to illustrate only some of the uses or lapplications of the invention which comprises the construction and relative arrangement of the battle platesv orshccts in a body of concrete. ,and such showing does not cover all the various uses or capabilities of the plates for water and damp-proofing concrete bodies.

ln carrying out my invention oppose, intercept. and cli'cctually cut-ofi. prevent., dissipate and destroy capillary attraction in an article or structure containing thc clements as sheets or plates of special constructionand relative arrangement which also affords reinforccnicnzs. tics or bonds for strengthening and unitizing said elements with theliod v of ccmcnt or concrete material containing thc saine.

Referring to Fig. i of the drawings. the concrete ashlar-hlock" has three sheets or plates 1 molded therein adjacent to its low temperatureface opposite its high temperature 'face 5i. Said sheets or plates are arranged parallel with each other and with said faces. and extend from end to end ofthe block and the top to the bottom faces ofthe block. Said plates arc duplicates in construction and each comprises a plurality of openings or perforations it for the passage and retaining of concrete bonding members 5 in a molding operation. The opening edges of the sheets or plates are preferably inturned as at so that in placing the plates for water or damp-proofing, said inturncd edges of one plate overlap like edges ot the adyaccnt plate or plates. with a filling and bonding space between the plates for aflayer or layers of colloidal tilling or strata of enriched concrete asf7. The plate. holes, openings or perforations 4 are preferably of thesame size and equal dis tance apart in each plate or sheet, and in proper molding position the openings l of certain plates alternate with the solid members 8 of adjacent plates, so that-in molding position of the plurality plates the center 'of the openings aand the center of the in-l tervening plate members 8 are on one common homologous axis as particularly shown .at a, a, a, a, Fig. 2. The area of the openings 4 being less than the area of the solid members 8, in approximate relation of 40 per cent openings and 60 per cent solids, so that by said relative arrangement of a plurality of plates as shown especially in' Figs. 1 and 4 of the drawings, the first plate adjacent the face 2 of a concrete body or block repels approximately 60 per centof the moisture or dampness enterin this face while .10 per cent thereof passing into theo bed or strata 7 through the bonds 5 is met,O opposed, out off and repulsed by the solid members 8 in the next or second plate, and should any dampness in a lesser or evaporated degree escape through the bonds or bond openings in the second plate such escape would be met, opposed and repulsed by the solid area or members 8 of the next or and horizontal position, with the block hollows 1() filled with rubble-concrete or broken:

stone and plastic material as 11. Figs. r6 and 7 illustrate. respectively, a hollow block 12 having baiie plates .and set upon a concrete base containing the damp-proof strata, provided with the baiiie` plates, and -said base has a lap point as 13, in the strata between the. plates. Fig. 8 illustrates myv water-proofed concrete hollow blocks in circular formation with double interlocking bed and header joints as 14:.'` This form embodies doublev strata intervened by the bocly concrete, andeach stratais rovided with double baiile plates. These b ocks are reinforced by a tension bar 15, and this particular construction is especially adaptable for the walls of circular containers such, for ex ample, as water and oil tanks, grain storage,

" silos and the like.

Figs. 9 and 10 illustrate the application of my invention to truss-reinforced wall slabs, andpaving flags when the'latter are laid flat or when used jointly in both flat and verticall positions for dampprooing the.

same, and the joints between.' The overlapped joint as 17 is made water and dampproof by having the solid portion of the baliie plates continuous and projecting beyond theJ joining edges of the slabs or flags, and these projecting portionsof the plates are folded in interlocked. position as at 18. The brace bar or Stringer 19y constitutes a reinforcement, and this structure may form damp-proof. walls and linings for various `receptacles and containers, aswell as mono lithic'concrete wallsand pavin The invention is shown applied in and to roofing tiles as illustrated in Fig. 13 of the drawings, wherein the baille plates are madev to'follow-the peculiar angles or forms of the tile as 20, and constitute a damp-proofing part thereof.

\ Fig. 14 shows the application of thevinvention to a brick wall 21,A having plastering 22 applied thereto, such plastering containing sheets of perforated water-proof fabric material 23 relatively arranged as hereinbefore described, the cement-stucco damp-proofing facing of the outer face of the brick wall being shown by thedotted lines 24.

Adverting t5 the modified form of baffling sheets or plates shown in Figs. 11 and 12, the same principle of alternating solid portions 25 andvfopenings or perforatlons 26 'id carried out as the sheets or plates lfere-A irlbefore described, butthese plates have relatively outwardly projecting angular points or ridges. 27 from which extend inwardly projectinglanges 28, forming the sides of the openings 26. When the sheets a square or angular cavity for the binding .or water-proof strata 29 and interlocked with said strata, as clearly shown in Fig.

12. In this form of plate as well as in the other form hereinafter) described, the bond openings of one plate being centrally' opposite the solid portions of the adjacent plate, and the inturned edges of said openings of the plates overlapping, prevents `direct capillary attraction. y y y As far as known` to applicant,` the ator plates are assembled, these flanges form tempts hereinbefore lmade to render concrete moisture and damp-proof,'have either completely insulated,' separated, and disbonded the faces-of a concrete body by inf.

terposing' solid sheets of walter-*and dampproof material therebetween, or bylreflyln'g upon'air chambers or spaces. Iformeel in the body of concrete by various means and de@ vices, or by having a concrete body -formed with separately functioning'walls lor faces having l`ttle structural'strength, value, So-

lidity an permanence. Such'attemptswhavel usually resulted in impairing the strutural strength and value ofa concrete bodytwall or structure.

isaavao Although 'I have shown and referred to the bao sheets for' concrete being of sheet metal, l do Inot wish to confine xn self to any particular niaterial,.nor to t esize,

shape and number 'of the .bond openings and intervening vsolid portions yof the sheetor relative proportions as and for the purposes hereinbefore stated, nondo l wish to limit myself in the application of the invention, but reserve the right to make such4 changes and 'variations therein and in the practical utility thereof as may not be inconsistent .'with the appended claims.

Having thus described my invention what I claim as new'and desire to secure by Letters. Patent is l. A damp-prooi concrete body, comprising a bedded 1n such body, with a bonding strata of cementitious material therebetween, said sheets havin alternate openings for said strata, and so id portions of greater area than said openings, said lsheets having such relative arrangement as to-locate the openings of one sheet centrally opposite the solid portions of the adjacent sheet. 2. .A damp-proof concrete body, comprising a pair of sheets, each of said sheets-havy in -like bent and"inturned 'openings and seid portions, embedded in such body of concrete or cementxnaterial, with a cement-itious colloidal bonding strata between'and through the intnrned openings of said sheets. I

3. A damp-proof concrete body, comprising a plurality of plates having alternate inturned openings and solid portions embedded in said body, with a plastic colloidal bonding strata therebetween, portions of said strata extending through the openings, and a greater portion of said strata being confined between said plates.

Il'. A damp-proof concrete body, comprising a .plurality ot bent edged perforated sheets embedded in said body in separate parallel larnnarposition, and parallel with opposite faces, a bonding stra-ta. between said sheets, extending therethrough and solidly bonding with the concrete of said body.

5. A damp-proof concrete body, comprising a plurality of perforated plates assembled within such body in separate parallel i plurality of perforatedV sheets ernvposition with the outer face of said body,

the perforations ot' one plate being in true registerin relation opposite the solid portions o t e adjacent plates, said perforations having inturned edges,l forming interlocking and interposing members with .the strata.

G. A damp-proof concrete body, compris--4 ing a plurality of perforated plates assembled within such body, with the perorations of one plate opposite the 'solid portions of the adjacent plates, a `bonding strata between and extending through the perforations of said plates, rabbeting and project- 1n said bodies forming a rabbeted and projectin interlocking damp-proof joint between said bodies.

'7. A damp-proof concrete body, comprisinga plurality of perforated sheets .assembody' comprising a tace layer ot cement material, a pervforated sheet of impervious material Vlaid upon said layer, a'layer ofbonding strata laid upon said sheet, a second like sheet laid upon the strata, with the 'perfor-ations of this sheet opposite the solid portions of the second sheet, a second layer Lof strata material, and a third sheet with its perforations truly, registering Awith the solid portions of'l said plates and bonding strata, from the .second sheet, and an inner or completing layer of concrete material laid upon the third sheet, lforming! under 'pressure a solid homogeneousl laminated body oidampproofed concrete. 1
